Upgraded from a functioning dual-boot Window 8.1 and Ubuntu 13.10 to 14.04. Before today at startup I option to choose Ubuntu or Windows8.1.

The default was Ubuntu, and if I waited a few seconds Ubuntu 13.10 would start with no action. Now machine boots straight to windows bypassing the old grub screen.

From Bios if I choose the right drive I get three options to boot to: Windows ubuntu Ubuntu, I can choose the last one and I am able to get Ubuntu 14.04 up. Installed boot repair and ran it info here:http://paste.ubuntu.com/7293152/ .... Would like to get the old boot screen....

Pls help.

Try to run a Grub Customizer from your Ubuntu installation, if you are lucky you will be able to revert and re-order your boot entries from there.

  • Ran Grub Customizer, it didn't change anything. Its almost as if there are two copies of Grub? Note the options to choose ubuntu or Ubuntu from bios. – cbudd Apr 20 '14 at 20:25
  • Then you should try to re-install the GRUB loader, as someone already suggested. – zgb Apr 20 '14 at 20:36

If normal 'Recommended Repair' of Boot-Repair does not solve your problem , you can try 'purging and re-installing grub' by selecting one of the options in 'Advanced Options' of boot-repair .

Click "Advanced Options" -> Select "Grub Options" tab -> Tick the "Purge GRUB and reinstall it" option --> Apply

For more details check https://help.ubuntu.com/community/Grub2/Installing

  • OK. Is this high risk? – cbudd Apr 20 '14 at 20:31
  • You can try it but read the "Purging & Reinstalling GRUB 2" section in this link https://help.ubuntu.com/community/Grub2/Installing before starting. – user223882 Apr 20 '14 at 20:40
  • Thanks it didn't seem to change anything. I tried it and I get an error message from boot-repair at the end.... – cbudd Apr 20 '14 at 21:22
  • what is the error ? – user223882 Apr 20 '14 at 21:23
  • The information is posted here I think: http://paste.ubuntu.com/7294250/ I only see the last lines on a final window before I am asked to restart. – cbudd Apr 20 '14 at 21:25
  • I noticed in boot-repair advanced Grub Options tab the Secure boot is ticked. Meanwhile that is turned off in my bios, maybe turning it off will help? – cbudd Apr 20 '14 at 21:35
  • yes you can try it. – user223882 Apr 20 '14 at 21:56
  • Still not booting Ubuntu - straight to Windows but now have Windows and Ubuntu as the options through bios. Before I had: Windows, ubuntu and Ubuntu. Boot repair says: The boot files of [The OS now in use - Ubuntu 14.04 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) – cbudd Apr 20 '14 at 22:27

  • I could not change the boot order from BIOS as indicated at that link but did run Boot-Repair --> Advanced Options --> tick the Backup and rename the Windows EFI files option --> Apply. To no avail....thanks for your help so far. Still boots windows without showing grub. – cbudd Apr 21 '14 at 16:42
  • Does this tell you anything? From grub customizer: recordfail load_video gfxmode $linux_gfx_mode insmod gzio insmod part_gpt insmod ext2 set root='hd0,gpt7' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt7 --hint-efi=hd0,gpt7 --hint-baremetal=ahci0,gpt7 766dbf2a-d437-4ab5-a521-8c6a8b48e0b5 else search --no-floppy --fs-uuid --set=root 766dbf2a-d437-4ab5-a521-8c6a8b48e0b5 fi linux /boot/vmlinuz-3.13.0-24-generic root=UUID=766dbf2a-d437-4ab5-a521-8c6a8b48e0b5 ro quiet splash $vt_handoff initrd /boot/initrd.img-3.13.0-24-generic – cbudd Apr 21 '14 at 16:46
